CB Carroll, G Williams visits Bills Wednesday

(WGR 550) -- The free agent visits have started for the Buffalo Bills, and the team has zeroed in on two players that would supplement their roster if it goes their way.

The Bills engaged in the courting process of both cornerback Nolan Carroll and guard Chris Williams by welcoming them to One Bills Drive for an official visit on Wednesday. Both players are unrestricted free agents.

Carroll, 27, spent his first four seasons in the NFL as a member of the Miami Dolphins and started a total of 26 games -- 22 of which happening in the past two seasons. In 2013, he had 47 tackles, three interceptions and two sacks for Miami as he filled in due to injuries.

Fitting the mold of what most the NFL is looking for at cornerback, Carroll has the prototypical big frame (6-foot-1, 205-pounds).

Williams, 28, is a former first-round draft pick of the Chicago Bears out of Vanderbilt back in 2008. He was selected 14th overall to play tackle for the Bears, but never established himself as a solid starter. He didn't start a game during his rookie season, but then started 38 games for Chicago from 2009 through 2011.

The Bears elected to cut ties with Williams just over a month into the 2012 season and days later he was picked up by the St. Louis Rams. He cracked the starting lineup for St. Louis in 2013, serving as their left guard in all 16 contests. Williams stands at 6-foot-6 and 326-pounds.

Both Carroll and Williams are unrestricted free agents. The only other visit the Bills are rumored to be having at this point is for former Tampa Bay linebacker Dekoda Watson, according to Mike Garafolo of Fox Sports 1.
